involvement_survey_str2s: Parent involvement survey: stratified, two-stage sample

Description

An example dataset describing a stratified, multistage sample of 1,000 parents of students with disabilities, from a population of 20,000. The parent involvement survey measures a single key outcome: whether "parents perceive that schools facilitate parent involvement as a means of improving services and results for children with disabilities."

The sample was selected by sampling 5 schools from each of 20 districts, and then sampling parents of 10 children in each sampled school. The variable BASE_WEIGHT provides the base sampling weight. The variable SCHOOL_DISTRICT was used for stratification, and the variables SCHOOL_ID and UNIQUE_ID uniquely identify the first and second stage sampling units (schools and parents). The variables N_SCHOOLS_IN_DISTRICT and N_STUDENTS_IN_SCHOOL can be used to provide finite population corrections.
